Poor screenwriting student + dinosaur = free offer

Any screenwriters out there who know how to work in DOS? Cleaning my office, I found the installation disks for the first screenwriting format program, Movie Master, a DOS program (on 3 5.25" floppies). This is a FIRST RATE program! I used it for years. No bells and whistles beyond format but it works like a charm for what it does. Free for the asking.
